Abstract：
Strawberry (Fragaria x ananassa Duch.) is a highly perishable fruit whose characteristics make it susceptible to developing microorganisms. Plant extracts have been studied as an alternative to pesticides to control spoilage microorganisms, responding to the expectation of the population seeking a healthier way of life. The fungus Botrytis cinerea is a facultative pathogen of vegetables, which can affect all stages of the development of several fruits, such as the strawberry, where it causes gray rot. Trichilia catigua (catuaba), Paullinia cupana (guarana), Stryphnodendron barbatiman (barbatimão), and Caesalpinia peltophoroides (sibipiruna) are planted in the Brazilian flora and have demonstrated pharmacological properties in their extracts. This work aimed to treat strawberries with a biodegradable film containing extracts of these species to evaluate strawberry conservation. There were notable distinctions in mass loss between the extract-treated and control samples. The pH, total acidity (TA), and soluble solids parameters exhibited consistently significant means across both sets of samples. Luminosity increased over the course of days in the color parameters, with the exception of strawberries coated with guarana. The red color showed greater intensity, except for those coated with barbatimão extract. Considering the results, it is possible to conclude that the coatings used can become an alternative to enhance the conservation of strawberries.
摘要：
草莓（FragariaxananassaDuch。）是一种高度易腐的水果，其特征使其对发育中的微生物敏感。已经研究了植物提取物作为杀虫剂的替代品来控制腐败微生物，回应人们寻求更健康生活方式的期望。灰霉病菌是蔬菜的兼性病原体，这会影响几种水果发育的所有阶段，比如草莓，会导致灰腐病。Trichiliacatigua(catuaba),Paulliniacupana(瓜拉那),木刺（barbatimão），和Caesalpiniapeltophoroides（sibipiruna）种植在巴西植物区系中，并已证明其提取物具有药理特性。这项工作旨在用含有这些物种提取物的可生物降解薄膜处理草莓，以评估草莓的保存。提取物处理的样品和对照样品之间的质量损失存在显著差异。pH值,总酸度（TA），和可溶性固体参数在两组样品中表现出一致的显著平均值。发光度在颜色参数的数天内增加，除了涂有瓜拉那的草莓。红色显示出更大的强度，除了那些涂有barbatimão提取物的。考虑到结果，可以得出结论，所使用的涂层可以成为增强草莓保护的替代方法。
